Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
210 words
A prefabricated wall unit construction comprising: a pair of horizontally spaced vertical columns of identical construction and a pair of vertically spaced horizontal channels of identical construction; bracket means connecting the end portions of said columns and channels to define a rectangular frame with the columns facing in opposite horizontal directions and the channels having their open ends facing upwardly and downwardly in opposite vertical directions; a rectangular core member of insulating material disposed in said frame; and a pair of rectangular siding panels of dimensions corresponding to the outside dimensions of said rectangular frame secured on opposite sides of said frame, said columns each including parallel rail portions of L-shaped cross section running vertically along a major portion of the exposed end edges of said columns; and clip means for straddling the L-shaped rail portions of one column with the L-shaped rail portions of an adjacent prefabricated wall unit identical in construction to said first mentioned prefabricated wall unit whereby a plurality of such prefabricated wall units may be aligned and secured by said clip means in series with their lower channels received over a common building floor sill and their upper channels received over a common ceiling sill to proviDe a continuous wall structure of any desired length.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
88 words
The subject matter of claim 1, in which said column members are H-shaped in cross section, the inwardly directed legs thereof straddling the adjacent side of said core and the outwardly directed legs thereof turning towards each other and thence inwardly to define said L-shaped cross section of said rail portions, said rail portions terminating short of the upper and lower ends of said columns, and said channels including cutouts at opposite ends to provide access for inserting said clip means over the ends of said rail portions.
Claim 4
Dependent Claim
70 words
The subject matter of claim 2, in which said clip means comprise substantially U-shaped members having an open ended toothed slot defined between the legs of the U for straddling adjacent L-shaped rail portions of aligned wall units, the outer edges of said legs including projecting ribs to provide a force fit of each leg of the clip means between the corresponding L-shaped rail and cross portion of the H-shape.
Claim 5
Dependent Claim
39 words
The subject matter of claim 2, in which said bracket means each comprise a member defining right-angle surface portions having projecting catches receivable in the inner right angle corners defined between the adjacent ends of the columns and channels.
